Classification / Names Κοινά ονόματα | Συνώνυμα | Catalog of Fishes(Γένος, Είδη) | ITIS | CoL | WoRMS | Cloffa

Ελασμοβράγχιοι (καρχαρίες και σαλάχια) (sharks and rays) > Heterodontiformes (Bullhead and horn sharks) > Heterodontidae (Bullhead, horn, or Port Jackson sharks)
Etymology: Heterodontus: heteros (Gr.), different; odontos (Gr.), tooth, referring to pointy teeth (for clutching prey) at front of jaws, different than rounded molar-like teeth (for grinding hard-shelled invertebrates) at the back. (See ETYFish);  galeatus: Latin for helmeted, probably referring to high, enlarged supraorbital ridges or crest. (See ETYFish).

Βιολογία     Γλωσσάρι (π.χ. epibenthic)

A moderately common benthic and epibenthic shark found on the continental shelf (Ref. 247, 43278). Occurs from close inshore to about 93 m depth (Ref. 247, 43278). Feeds primarily on sea urchins, but also on crustaceans, mollusks, and small fishes (Ref. 31369). Oviparous, egg cases spirally flanged and with long tendrils (Ref. 6871). Hatches at about 22 cm (Ref. 6871).

Life cycle and mating behavior Maturities | Αναπαραγωγή | Spawnings | Egg(s) | Fecundities | Προνύμφες

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace (Ref. 205).
